“…The broader peak of the fcc alloy demonstrated in Fig. 8 reflects the amorphous character of the thin film alloys [14]. In this study, it was revealed that the use of ITO as the substrate led to the formation of amorphous phase, which agreed well with the findings of other workers [36,37].…”

“…Over recent years, the fabrication of Co-Ni-Fe ternary alloys thin film is done through various techniques such as positive microemulsion [12] and electrodeposition [13]. The electrodeposition is a prevalent method among the techniques in producing metallic alloy films [14] as the method is economic [15] with wide range industrial applicability [15]. In electrodeposition method, experimental parameters like electrodeposition potentials [16] and electrolyte condition (composition, temperature, additive and pH) can alter the deposition product properties.…”

The aim of this study was to produce thin films of ternary cobalt-nickel-iron (Co-NiFe) alloy by electrochemical deposition method at different electrodeposition potentials in a sulfate solution (0.15 M CoSO 4 + 0.2 M NiSO 4 + 0.005 M FeSO 4 ). The Co-Ni-Fe alloy thin films were electrodeposited on indium-doped tin oxide (ITO) coated on a conducting glass substrate. Voltammetric studies indicated the potential range between -1.10 to -1.30 V (SCE) for successful deposition of Co, Ni and Fe. The energy dispersive X-ray (EDX) analysis indicated that the films exhibited anomalous behavior with Ni content significantly increased, whereas the Co and Fe content decreased as the electrodeposition potentials reached more negative values. The scanning electron microscopy (SEM) study showed that the electrodeposited films were uniform for all applied potential values and larger particles were formed when higher electrodeposition potentials were applied. Investigation by X-ray diffraction (XRD) revealed that the dominant phase in the deposited film was amorphous Co-Ni-Fe. Hysteresis curves of the ternary alloy film obtained from vibrating sample magnetometer results prove that the alloy is ferromagnetic. The coercivity mechanism of the Co-Ni-Fe films has obeyed Neel's relation which is thickness dependence.

“…* evaluated as hyperfine field distributionThe 119 Sn Mössbauer results are consistent with the occurrence of a dominant ferromagnetic and a minor paramagnetic amorphous Sn-Fe-Co-Ni phase as was shown by the 57 Fe Mössbauer and XRD results, similarly as in the cases of the ternary alloys[1][2][3].…”

“…In order to find suitable conditions for electrodeposition to achieve multicomponent alloy deposits without segregation of equilibrium binary phases was the fundamental basis for this research study. 57 Fe and 119 Sn conversion electron Mössbauer spectroscopy (CEMS), and X-ray diffraction (XRD) proved to be excellent tools to characterize the electrodeposited alloy coatings [1][2][3]. In the present work novel Sn-Fe-Co-Ni alloy coatings were deposited by constant current method on copper substrates from an aqueous gluconate based electrolyte.…”

A constant current technique electrochemical deposition was used to obtain quaternary alloys of Sn -Fe-Co-Ni, which to date have not been reported in the literature, from a gluconate electrolyte. For the characterization of electroplated alloys 57 Fe and 119 Sn conversion electron Mössbauer spectroscopy (CEMS) and XRD were used. XRD revealed the amorphous character of the novel Sn-Fe-Co-Ni electrodeposited alloys. 57 Fe Mössbauer spectrum of quaternary deposit displayed a magnetically split sextet with broad lines typical of iron bearing ferromagnetic amorphous alloys. Magnetically split 119 Sn spectra reflecting a transferred hyperfine field were also observed. New quaternary Sn-Fe-Co-Ni alloys were successfully prepared.

Abstract:Characterisation of Sn-Ni-Fe ternary alloy deposits obtained by pulse electrodeposition show that novel alloys of varying composition can be successfully deposited exhibiting amorphous structures using specific on/off pulse plating parameters for electrodeposition in combination with an electrolyte based on gluconate as a complexing agent. The deposits obtained exhibited high quality bright metallic surface morphologies combined with a distinct pronounced spherical/nodular grain structure across a range of average current densities. The influence of on/off period pulse current and the effect of the average current density on the surface morphology of the electrodeposited films were studied using Scanning Electron Microscopy (SEM). The cathode efficiency results obtained show that the pulse electrodeposition process chosen is significantly more efficient than the constant current electrodeposition. Results suggest that the substrate surface deformation condition and preparation are critically important in achieving a surface morphology suitable for an effective Sn-Ni-Fe alloy battery electrode. The alloy deposits with a morphology, which exhibits a high surface area per unit volume, are shown to be promising as an alternative anode material for lithium ion batteries.
